This post should really be in the Playstation 2 discussion room, but oh well.

You need to download the PS2 Media Player software and convert the DivX file in the program. This then creates a BIN/CUE file which you then burn onto a disc. It should then work.

There are easier ways I have heard but I haven't used my mediaplayer in ages. I think you can load the media player into the memory card and do a direct boot, but I haven't tried that and you might want to look into it by searching the forum. I hope this has helped a little.

Im thinking also that the file needs to be in the format of .avi and not .img.
